Ok so i just replaced the tps on my xj and cleaned the idle air control valve, and still get a slight vibration when my jeep is at idle. I have noticed that the rpm's do spike up when it does this. What could this be? Should i just replace the idle air control valve all together? i have a 99 xj 4.0 with about 160xxx miles
